Looking for a hand troubleshooting my issue.

I got my A/C functioning the other day, but since I purchased the car, the air has never blown out of the vents very hard. No matter what setting the fan is set to, or if its set to hot or cold, outside air or set to recirculate, or floor, dash, or defrost mode. It always just blows out weak.

The first thing I have checked is the fan motor. I pulled it out and turned it on and its perfectly fine. Same as the fan motor in my other DSM, but my other DSM blows out super hard.

The air dampers around the heater core, no matter what settings you have it set to, always have some path open for the air to flow through, same for the dampers above the blower motor.

What else should I look at? Is it possible that the A/C evaporator can get so clogged and dirty that it restricts the air flow? I can't really see into it without removing it and the A/C lines that connect to it. Trying to rule out anything else before I go down that route.

Any help is appreciated!
 
Ac evaporator is most likely clogged. May have a mouse nest. When i removed my evaportaor it was packed solid with a mouse nest. Now my blower motor is like a hurricane haha. You can remove the blower motor side of the hvac box and look inside. Its tight under the dash but doable.
